Romance a special one? Not half! (5)
I believe the answer is:
amour
'romance' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for amour that I've seen before include "Romantic affair" , "Affair of the heart" , "Affaire" , "Illicit love" , "Romantic liaison" .)
